Abstract

The development of eye safe fiber lasers for wavelengths with high transmission through the atmosphere, capable of operating single wavelength at short pulses ( |1ns), high pulse energy, high average power, and high beam quality, require the development of appropriate active fiber designs as well as beam coupling concepts consistent with application requirements. These lasers can find use in long range target ranging and tracking systems such as the Active Ranging Sensor for the Airborne Laser System, in which case the proposed laser will allow precision ranging down to a few centimeters and high accuracy acceleration measurement, therefore, accurate trajectory determination. It can also be designed for space applications related with terrain mapping and sounding of the atmosphere, for which it will allow to obtain high range resolution.
